/* K9solutions, night edition
   Idea: a calm control room after dark. Deep navy from the logo's background, a glow taken from the
   Siamese cat's sapphire eyes, and the cream of its coat for warmth. Products float on glass;
   one 3D display in the hero is the only showpiece, everything else stays quiet and precise. */
